Issue 17 | Axum Asynchronous Web Framework

Sharer: Zhang Handong

【 Topic 】

  1. Axum’s middleware is an abstraction that uses tower directly, and the benefits are: A. A unified Service and Layer abstraction standard is used to facilitate the prosperity of the ecosystem. Reuse tokio/Hyper/Tonic ecology

  2. Axum’s routing mechanism provides a simple DSL (chain call). Routes are matched based on iteration and regular expressions

  3. It also provides a convenient extractor, and as long as you implement FromRequest that’s an extractor, it’s very easy to implement.

Issue 18 | How to Implement RPC Framework with Rust

Sharer: Zhang Handong

【 Topic 】

  1. Tutorial author FmHai shared the idea of Lust framework. Why rust? Because the performance of the GO service has reached a bottleneck of inventory optimization, rust reimplementation has to be considered to fundamentally eliminate the problems caused by the GO system.
  2. Follow along to learn how to build an RPC framework. The tutorial is short, but informative, and incorporates a lot of thinking into production practices.
    • Chapters 2 through 3 cover how to abstract messages and protocols,
    • Chapters 4 and 5 show how tokio Codec and Transport can be combined to further integrate messages and protocols, as well as using Tower to increase middleware support and reuse tools from the Tokio ecosystem.
    • Chapter 6 shows you how to use nom to parse thrift IDL and how to generate code automatically through procedure macros.
    • Chapters 7 and 8 further build on Tower to add service discovery/liability balancing/custom middleware features. Small as the sparrow is, it has all the organs and is worth learning from.

Web3.0 application chain development

Speaker: Lester

Overview of Web3.0:

  1. Web3.0 a new phase of a more open, fair and secure Internet.
  2. Web3.0 applications [community-owned encryption protocols] replace [company-owned platforms].
  3. The landing of Web3.0 applications requires comparable user experience and service capabilities of Web2.0 applications.

The development of application chain by Substrate framework is emphasized.

Web3.0 privacy computing system design

Speaker: Zhou Shunfan

Phala Network is a Network that tries to provide private computing to blockchain. Through what kind of technical means and system design, contractual privacy, security and overall performance are guaranteed.

Akash open source cloud computing marketplace

Speaker: Uncle Red Army

Akash a decentralized Amazon cloud or Ali Cloud. The current situation of cloud computing is monopolized by four giants (Amazon cloud, Google cloud, Ali Cloud and Microsoft Cloud), which ultimately harms the rights and interests of users. Akash leveragesblockchain features and virtualization container technology to provide a decentralized version of cloud computing.

Web3.0 storage and trusted computing

Speaker: Xiong Wei

During the development process, I encountered many problems, including the high cost of miners and the high threshold of users. These problems have been bothering the developer. Last year, I participated in the Ethereum MeetUp organized by Spark organization and had a new idea, using a block chain to build a new application.
